Clean up CodeIgniter's database (ActiveRecord) memory usage

As what I have found when I was researching there are 2 ways:

• Prevent ActiveRecord from saving query

by

$this->db->save_queries = false;

credit: how can I free the memory used by $this->db->insert()

• Free result memory - CodeIgniter will only reclaim memory when http query processing was returned. If you request is long, you have to free by yourself

by

$query = $this->db->query('SELECT title FROM my_table');
$query->free_result();

Useful VIM command that I still can't remember

• “0p - pastes the last explicitly copied text
• :reg - Show a list of registers
• J - Merge current line With Next Line
• =, == - Fix indention
• u,U(in visual mode) - lower, uppercase
• q: - list command history
• q/ - list search history
• Ctrl ^ - go to previous buffer
• :w !sudo tee % - save readonly file
• diw - delete a word
• di(, da( - delete text inside/include ()
• di", da" - delete text inside/include ""

For rails.vim

• gf - open file from cursor
• :R{view,model,controller,spec} {file}

Git - Global gitignore

Some types of temporary files are spanding across project, such as .swp (VIM temporary file type).

To put *.swp to every project's repositories makes duplicate job.

One way to solve this issue is to put it to Global gitignore.

From this blog Git global ignores, i will copy to here, also.

- Create .gitignore file at somewhere, mostly at ~/

git config --global core.excludesfile ~/.gitignore

- An pattern of file, you want to do global ignore in to that file.

That's it.

[VIM] Mostly use FuzzyFinder and NERDTree shortkeys

Basic VIM
- Open new horizontal split :sp file
- Open new vertical split :vs file
- Switch between split pane: Ctrl-w + { h|j|k|l }
- Rotate pane down/right: Ctrl-w + r
- For more, see Vim documentation: windows

FuzzyFinder
- Open in vertical split: Ctrl-k
- Open in horizontal split: Ctrl-j

NERDTree
- Open in vertical split: s

[Solved] autoscan: not found

If you are in process of compiling something on Ubuntu and you get error similar to these

./bootstrap.sh: 24: autoscan: not found

You have to install autoscan program but you can not find autoscan with

sudo aptitude search autoscan

The package name you have to install is autoconf. I don't know why because I'm not an expert on C/Linux but after below command, the compilation works.

sudo apt-get install autoconf

Create simple Ubuntu(Debian?) start up script

- Create a file at /etc/init.d/<filename>

#!/bin/bash

case "${1:-''}" in
'start')
# put the command to start
;;
'stop')
# stop command here
;;
'restart')
# restart command here
;;
*)
echo "Usage: $SELF start|stop|restart"
exit 1
;;
esac

sudo update-rc.d <filename> defaults

sudo /etc/init.d/<filename> <start|stop|restart>

- To remove

sudo rm /etc/rc*/*<filename>
